Just the opposite. It's not a real repair I would do when repairing a clarinet, but a quick, completely reversible, easy way to fix the problem. Nothing extreme about it at all.

>> Backing out is symptomatic of the binding occurring along the points where the key needs to move freely around the rod or pivot. <<

Sometimes. In the case of the OP, he specifically said he purposely leaves the screw not tightened because otherwise it binds the other key. If the threads are not tight (and they often aren't) then there's more friction between this long screw and hinge than anywhere else. If the screw is not tightened then it makes sense that it moves with the key (even if oiled). It also makes sense that it screws itself out and not in, since this is the direction that will remove friction from the threads instead of adding more friction.
